Qt Assistant for Windows XP

  • Hi,

    I was wondering if there is also a Windows XP version for the Qt Assistant?
    I compiled my application with 'msvc_140_xp' and 'Qt 5.8', it is working without any additonal changes.

    The only problem is the Qt Assistant does not run under XP.

    I hope someone can point me in the right direction!

    Kind regards,

    What about just compiling Qt Assistant with same setup as your app?
    It should run then unless i missed something.

    Why dont it run under xp ?
    What happens?

    (sorry xp have been dead for year for me so i have no way of testing)

  • Thank you for your answer. I figured out how to compile Qt Assistant for Windows XP.

    The only thing you need to add to the qtassistant.pro file is the following code:

    win32 {
        contains(QMAKE_TARGET.arch, x86_64) {
            message("Building Xp 64")
        } else {
            message("Building Xp 32")

    And ofcourse you need to have the MSVC toolkit installed for XP. That's the msvc_140_xp toolkit.

    Super, thank you for reporting back with exact solution.
    Even xp should be dead , with dead on top, it seems there are still many out there :)

  • Yes xp should be dead, but if your application is serving many XP users it's nice to still have the option.

    Indeed. Xp still works fine. its just not safe to use near internet.
